Abstract

1409200 Contact arrangements SIEMENS AG 18 April 1973 [19 April 1972] 18678/73 Heading H1N A change-over contact arrangement comprises two contact springs 6, 7 biased toward a central fixed contact 8 and controlled by a common operation element 5 and the central fixed contact is bifurcated to form contact arms 9, 10 which are off-set from each other in the direction of contact movement. The operation element or card 5 has a lateral slot 11 for the spring 7 and the spring 6 engages the end of the card remote fron an armature 4. When the relay coil 2 is energized the armature 4 moves the card 5 to open contacts 6, 9 and permit contacts 7, 10 to close. On de-energization a return spring 12 moves the card 5 to open contacts 7, 10 an permit contacts 6, 9 to close.
